Objective:To explore the Chinese medicine to reduce red blood cell transfusion mechanism, anemia treatment and provide a theoretical basis for patients with severe hypoxic ischemic symptoms.Methods: in our hospital from 2012 May to 2013 May in our hospital were severe anemia in 96 cases, according to the order of admission, were randomly divided into study group(48 cases) and control group(48 cases), study group was treated with Chinese medicine Yiqi Buxue cream treatment, the control group using sugar iron injection treatment, treatment effects were compared between the two groups.Results: the treatment group the total effective rate was 97.9% in treatment group, the total effective rate was 87.5%, and there was significant difference between two groups(P<0.05). Study group Hb after treatment was (106.43±13.08) g/L, the control group after treatment Hb(98.69±14.25)g/L, there was significant difference between two groups(t=13.26,P<0.05). After treatment, study group MCV, MCH, MCHC improvement, compared with the control group with statistical significance; the two groups in the improvement of red blood cell morphology were obvious effect, and the study group was better than control group. Statistical significance of group SF after treatment and the control group at the same time difference(t=11.28,P<0.05). The control group had 10 cases of gastrointestinal discomfort, study group 1 cases of no adverse reaction.Conclusion: TCM symptoms of Chinese medicine Yiqi Buxue cream treatment can significantly improve the syndrome of blood deficiency of iron deficiency anemia, reduce the number and the number of red blood cell transfusion, clinical curative effect, less adverse reaction.

Based on Ag nanoparticles as the surface-enhanced Raman spectroscopy (SERS)-active nanostructure, the SERS of uric acid was presented in the paper. The absorption spectroscopies of uric acid and the mixture of silver colloids and uric acid were measured. The possible enhancing mechanism of the uric acid on silver colloid was speculated. The characteristic SERS bands of uric acid were tentatively assigned. The influence of absorption time and different ion on the SERS of uric acid were also discussed. The SERS spectral intensity changes linearly with the uric acid concentration, which indicated that the SERS might provide a new kind of direct and fast detecting method for the detection of uric acid. The detection limit of uric acid in silver sol is found to be 1 mg/L.

Objective:To examines the social health status and influencing factors affecting the elderly population in urban communities of Beijing, based on the "the Standard for Healthy Chinese Older Adults(2022)" .Methods:Using the stratified sampling method, a total of 159 elderly individuals aged 60 and above from the Lanyuan community in the Malianwa street jurisdiction of Haidian district, Beijing, were selected as research subjects.The average age of the participants was(70.7±7.9)years, comprising 74 males and 85 females.Household face-to-face interviews were conducted, utilizing self-compiled questionnaires to perform a comprehensive assessment and analysis of the social health status of the elderly.Results:In the study involving community-based elderly participants, 32.1%(51 cases)were classified as healthy.The analysis revealed statistically significant differences in the social health status among various age groups of the elderly( χ2=11.802, P=0.019), with a notable downward trend in social health status as age increases( χ2=9.626, P=0.002).Furthermore, the results of multivariate Logistic regression analysis indicated that educational level( OR=2.119, 95% CI: 1.044-4.031, P=0.038)and chronic disease status( OR=5.007, 95% CI: 1.083-23.140, P=0.039)are significant influencing factors on the social health status of older adults. Conclusions:The social health status of the elderly in urban communities in Beijing is generally low and deteriorates progressively with age.Both educational attainment and chronic disease prevalence significantly influence the social health of this demographic.For elderly individuals with lower educational levels and poor chronic disease management, it is essential to conduct social health assessments and implement targeted intervention strategies to enhance their overall social health.

BACKGROUNDA practical problem impeding clinical translation is the limited bone formation seen in artificial bone grafts. Low-pressure/vacuum seeding and dynamic culturing in bioreactors have led to a greater penetration into the scaffolds, enhanced production of bone marrow cells, and improved tissue-engineered bone formation. The goal of this study was to promote more extensive bone formation in the composites of porous ceramics and bone marrow stromal cells (BMSCs).

METHODSBMSCs/β-tricalcium phosphate (β-TCP) composites were subcultured for 2 weeks and then subcutaneously implanted into syngeneic rats that were split into a low-intensity pulsed ultrasound (LIPUS) treatment group and a control group. These implants were harvested at 5, 10, 25, and 50 days after implantation. The samples were then biomechanically tested and analyzed for alkaline phosphate (ALP) activity and osteocalcin (OCN) content and were also observed by light microscopy.

RESULTSThe levels of ALP activity and OCN content in the composites were significantly higher in the LIPUS group than in the control group. Histomorphometric analysis revealed a greater degree of soft tissue repair, increased blood flow, better angiogenesis, and more extensive bone formation in the LIPUS groups than in the controls. No significant difference in the compressive strength was found between the two groups.

CONCLUSIONLIPUS treatment appears to enhance bone formation and angiogenesis in the BMSCs/β-TCP composites.
