Objective To explore the clinical significance of the combined application of palpebral margin cleaning and antibiotic eye drops in inhibiting bacterial growth in the palpebral margin and conjunctival sacs before cataract extraction. Methods In this study, 61 patients (97 eyes) with age-related cataract who underwent phacoemulsification and intraocular lens implantation were selected, and randomly grouped. In the experimental group, the combined application of palpebral margin cleaning with cotton pads and levofloxacin eye drops was given for three days before the surgery. In the control group, levofloxacin eye drops alone were applied for three consecutive days. Bacteria samples from the conjunctival sac and eyelid margins were cultivated and identified before and three days after taking antimicrobial measures, respectively. Results In the experimental group, the positive rates of the two bacteria samples were 100% (50/50) and 40% (20/50) before and 10% (5/50) and 0% (0/50) after the treatment. In the control group, the positive rates of the two bacteria samples were 97.9% (46/47) and 29.8% (14/47) before and 40.4% (19/47) and 10.6% (5/47) after the treatment. The positive rates between the two groups were not significantly different before taking antimicrobial measures (P= 0.485 and 0.395), while they were significantly different after taking antimicrobial measures (P = 0.001 and 0.024). Conclusion Combined application of eyelid and palpebral margin cleaning with cotton pads and antibiotic eye drops before cataract extraction imparted excellent antibacterial effects.
A 2-year-old girl was diagnosed as Weill-Marchesani syndrome with typical systemic features of short stature, short and stubby hands and feet, language disorders and mental retardation. He developed bilateral angle closure glaucoma, ectopia lentis and suffered visual loss from the ocular features of Weill-Marchesani syndrome. The child was successfully treated by combined CO2 laser-assisted sclerectomy surgery and trabeculectomy.
The mode of scientific thinking is undergoing rapid and profound changes. In the 21st century, macro and micro civilizations go parallel. A systematic and scientific methodology is required for the study of complex things. The thinking mode in modern medicine is gradually shifting from analytical, reductive thinking to holistic and systematic thinking. As such Western medicine and traditional Chinese medicine are gradually approaching the epistemology of health and disease state. The importance of scientific thinking in innovation has been expounded in this study. The development trends in medicine in the current era are analyzed, the importance of systems theory in the study of human bodies is discussed, and a new medical model named Novel Systems Medicine is proposed.
Considering the limitations of medical science and the risks associated with medical treatments, we need to re-examine the connotation of medical science from the perspective of philosophy. Medical science is the natural expression of human kindness and human nature of rescuing the dying and healing the wounded. It is a combination of the natural sciences, social sciences, and humanities. From the perspectives of medical philosophy and humanistic care, this article expounds the concepts and ideas of evidence-based, translational, and precision medicine in modern medicine and emphasizes the importance of avoiding new technical bureaucracy, paying attention to achieving a holistic view and systematic understanding, and avoiding biases in development because of the loss of the humanistic spirit in modern medical practice.
The 19th National Congress of the Communist Party of China has proposed a national strategy for a healthy China, which includes the formulation of a new plan to promote high-quality development. Oral diseases have been included in the national “Medium- and Long-term Plan for the Prevention and Treatment of Chronic Diseases”. China’s national oral health strategy provides great opportunities for advancements in stomatology and for the improvement of the people’s oral health. This article discusses these opportunities for advancement in the field of stomatology in China from six aspects: societal needs of oral health; advances in science and technology; changed diagnosis and treatment modes; application of big data; multidisciplinary integration; and talent training.
The burden of dental diseases is increasing in the Chinese population. However, the development of the dental industry falls behind the average development level of medical industry in China. The emergence of digital dental technologies has created significant opportunities for the development of the dental industry in China. This article explores the innovative development background of the Chinese dental industry, describes the current innovation status in Chinese medical colleges and enterprises, highlights key problems faced by the nation, enterprises, and hospitals, proposes solutions to these issues, and puts forwards a new concept of building an open and collaborative service system, a transformation path, and a whole-chain support system for innovations in dentistry.
Objective To examine the neuroanatomical substrates underlying the effects of minocycline in alleviating lipopolysaccharide (LPS)-induced neuroinflammation. Methods Forty C57BL/6 male mice were randomly and equally divided into eight groups. Over three conse-cutive days, saline was administered to four groups of mice and minocycline to the other four groups. Immediately after the administration of saline or minocycline on the third day, two groups of mice were additionally injected with saline and the other two groups were injected with LPS. Six or 24 hours after the last injection, mice were sacrificed and the brains were removed. Immunohistochemical staining across the whole brain was performed to detect microglia activation via Iba1 and neuronal activation via c-Fos. Morphology of microglia and the number of c-Fo-positive neurons were analyzed by Image-Pro Premier 3D. One-way ANOVA and Fisher’s least-significant differences were employed for statistical analyses. Results Minocycline alleviated LPS-induced neuroinflammation as evidenced by reduced activation of microglia in multiple brain regions, including the shell part of the nucleus accumbens (Acbs), paraventricular nucleus (PVN) of the hypothalamus, central nucleus of the amygdala (CeA), locus coeruleus (LC), and nucleus tractus solitarius (NTS). Minocycline significantly increased the number of c-Fo-positive neurons in NTS and area postrema (AP) after LPS treatment. Furthermore, in NTS-associated brain areas, including LC, lateral parabrachial nucleus (LPB), periaqueductal gray (PAG), dorsal raphe nucleus (DR), amygdala, PVN, and bed nucleus of the stria terminali (BNST), minocycline also significantly increased the number of c-Fo-positive neurons after LPS administration. Conclusion Minocycline alleviates LPS-induced neuroinflammation in multiple brain regions, possibly due to increased activation of neurons in the NTS-associated network.
