Objective To analyze the frail status and influencing factors of inpatients in geriatrics department.Methods A total of 170 patients aged ≥ 65 years in Geriatrics Department in our hospital were selected.Frailty was defined according to the Clinical Frailty Scale (CFS),and patients were divided into non-frail group and frail group.The differences in comorbidity,physical function,nutrition,cognitive,psychological,geriatrics syndromes,medication,social support and other aspects were analyzed between the two groups by using Comprehensive Geriatrics Assessment(CGA),and correlationof the factors with frailty was evaluated.Results There were 83 (49.0％)patients in frail group and 87 (51.0％)in non-frail group.In frail group versus non-frail group,Charlson comorbidity index was(2.7±2.0)vs.(1.9±1.1),and cumulative illness rating scale was(10.8±3.7) vs.(8.0±2.6) (all P＜0.05);mini-nutrition assessment was(11.2±2.3)vs.(13.0±1.3),and simple cognitive score was(2.7±1.3)vs.(4.1±0.9)(all P＜0.05).Grip,five chair rising,timed get-up and go test,walking speed,SPPB showed statistically significant differences (all P＜ 0.05) between frail group and non-frail group:(20.7±6.6)kg vs.(27.96.7)kg,(30.4±17.5)vs.(12.9±4.1),(23.7± 9.9)vs.(11.7± 3.3),(0.5 ± 0.2)m/s vs.(0.9± 0.2)m/s,(5.6 ± 2.3) vs.(10.3±1.8)respectively.The incidences of incontinence,visual impairment,hearing impairment,sleeping disorder,oral problems,chronic pain,anxiety or depression and fall history were higher in frail patients than in non-frail patients.Living alone,the widowed,nursing staff employment proportion were higher in frail group than in non-frail group.Level of education was lower in frail group than non-frail group.Logistic regression analysis showed that BMI,the walking speed and the number of geriatrics syndromes had a significant impact on frailty(OR=0.789,0.000,2.745,all P＜0.05).Conclusions Incidence rate of frailty in elderly hospitalized patients is high.To identify frailty of hospitalized patients,comprehensive geriatric assessment can be used for understanding frail characteristics and its influencing factors for hospitalized old patients,so as to provide evidence for the reasonable treatment programs.

Objective To study the effect of Haikun Shenxi Capsule(HSC)on endothelin-1(ET-1)and mRNA expression of rats with adriamyein-induced nephrosis and proliferation of glomerular mesangial cells(GMCs)cultured in vitro.Methods The rats were randomized into 6 groups,normal group,sham operation group,model group,benazepril group,HSC low-and high-dose groups.Ten weeks after treatment,ET-1 and mRNA expression were measured with immunohistochemical and hybridization in situ method.Tak- ing the Benazepril group as the control group,the proliferation of GMCs was detected with MTT method.Results In the model group,ET-1 and mRNA expression presented a strong positive,compared with which,that of the HSC low-and high-dose groups was remarkably reduced(P

Objective To explore effects of heat stress response on neutrophil apoptosis and respiratory burst function. MethodsNeutrophils from each of 18 healthy volunteers were divided into 3 parts,and one part was served as control group,and the other two parts were induced by heat shock or cadmium chloride for heat stress response and named as heat shock group and cadmium chloride group.The neutrophils were incubated in culture medium.At 0,2,3,4,and 6 h following heat stress induction,the heat shock protein(HSP70) expression and the respiratory burst were detected in the neutrophils respectively by using PCR technique and flow cytometer.Level of apoptosis was observed by immuno-fluorescence and flow cytometer DNA ploid at 24 h after heat stress induction. Results In the heat shock and cadmium chloride groups,HSP70 expression at each time point and cell apoptosis at 24 h were significantly higher than those of control group(P

0.05). Conclusion Enough high-purified LECs can be isolated by collagenase digestion procedure followed by immunomagnetic beads sorting. Post-thawed endothelial cells are proved to have high vitality and growth potential in vitro without significant morphological changes. Cryopreserved LECs may serve as a cell choice for research of lymphangiogenesis and lymphatic patterning.

Because of the population aging,the increase of the stroke patients and the need for rehabilitation,the treatment only in the rehabilitation department of the hospital is far from the satisfaction of people's demands of the service of rehabilitation.It is important to extend the community-based rehabilitation.Compared with the rehabilitation in hospitals,it is more economy,efficiency and convenience for stroke patients in community-based rehabilitation services,and further improve the rehabilitation effect of stroke patients.

Objective: To observe the effect of different moxibustion durations on rats with rheumatoid arthritis (RA) and to evaluate the relationship between moxibustion amount and moxibustion efficacy.Methods: Eight rats were randomly selected as a normal group from the 40 male Sprague-Dawley (SD) rats, and the other 32 rats were used to establish typeⅡ collagen-induced RA models. After successful modeling, the 32 rats were randomly divided into a model group, a moxibustion for 20 min group, a moxibustion for 40 min group and a moxibustion for 60 min group, with 8 rats in each group. Rats in the normal group did not receive modeling and moxibustion intervention; rats in the model group did not receive moxibustion after modeling; rats in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group were treated with moxibustion at Shenshu (BL 23) and Zusanli (ST 36) for 20 min, 40 min and 60 min, respectively. Six days were a course of treatment, with a total of 3-course treatments and a 1-day rest between the courses of treatment. After treatment, the serum levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α, arthritis index (AI) scores, toe volumes and pathological score of synovitis were evaluated in the rats.Results: Compared with the normal group, the serum IL-1β and TNF-α levels, and the toe volumes in the model group were increased, and the differences were statistically significant (P<0.01), before the treatment. Compared with the model group, the serum IL-1β and TNF-α levels, toe volumes and arthritis index (AI) scores were significantly decreased in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group (P<0.05 orP<0.01 ). Compared with the moxibustion for 20 min group and the moxibustion for 60 min group, serum IL-1β and TNF-α levels, toe volumes and AI scores were decreased more significantly in moxibustion for 40 min group, and the differences were statistically significant (P<0.05 orP<0.01). There were no significant differences in serum IL-1β and TNF-α levels, AI scores and toe volumes between the moxibustion for 20 min group and the moxibustion for 60 min group (allP>0.05). The synovial histopathological improvement was the most obvious in the moxibustion for 40 min group, when the synovial histopathological changes were compared among the moxibustion for 20 min group, moxibustion for 40 min group and moxibustion for 60 min group.Conclusion: The therapeutic efficacy of moxibustion for 40 min in RA rats was more significant than that of moxibustion for 20 min and moxibustion for 60 min, indicating that the duration of moxibustion is the main factor affecting its therapeutic efficacy.

Objective To analyze the characteristics of TCM syndromes of children abnormal sweating;To investigate the correlation between diseases and primary and secondary syndromes. Methods Through a multi-center epidemiology investigation, 400 cases were collected to statistically analyze the five TCM syndromes of children abnormal sweating, and characteristics of each syndrome were analyzed. Results In the 400 cases of children abnormal sweating, there were 129 cases (32.25%) of dysfunction of lung-wei pattern, 50 cases (12.50%) of nutrient qi and defensive qi discordance, 84 cases (21.00%) of qi and yin deficiency pattern, 57 cases (14.25%) of dampness heat forced steamed pattern, and 80 cases (20.00%) of qi and yang deficiency pattern. Spontaneous sweating and night sweating were found in the four patterns besides qi and yin deficiency pattern, and night sweating can be mainly found in qi and yin deficiency. Each type is consistent in the syndrome differentiation and cluster analysis. Conclusion Spontaneous sweating and night sweating, each has the certification of yin and yang. Spontaneous sweating can be caused by yin deficiency while night sweating can be caused by yang deficiency. Each pattern of children abnormal sweating has its own syndrome characteristic, which can provide the basis for clinical diagnosis and treatment.
