A method and apparatus for detecting the presence of the viable cells in an endodontic sample in or taken from an endodontic cavity in the tooth, such as the root canal, enables the rapid and low cost identification of the presence or absence of bacteria or other viable cell tissue in the endodontic space by first incubating a viable cell indicator with an endodontic sample for a pre-determined period suitable for chair-side test and then measuring and / or detecting a change in a parameter (e.g. fluorescence) associated with the viable cell indicator. Thereby, the required level of root canal treatment can be reached which minimizes the risk of re-infection without the time, cost and potentially harm of over-preparation and over treatment by the dental surgeon or of a re-treatment.

Embodiments of the present invention provide a diagnosis and treatment information processing method, server, and system. When a user inputs symptom information, the physiological index information of the user collected in real time by the somatosensory network is screened according to the correlation rule of symptom-physiological index, and removed. Physiological index data that is less relevant or irrelevant to the symptom, and then cut out the diagnosis and treatment items in the standard diagnosis and treatment template according to the filtered physiological index data and the elimination rules of the set diagnosis and treatment items in the specific physiological index state, Finally, the trimmed diagnosis and treatment template will be distributed. The present invention uses the user's physiological index information acquired by the somatosensory network in real time, and performs preliminary processing on the physiological index information, which reduces the noise information irrelevant to symptoms, makes the diagnosis and treatment process more objective, and realizes the user's diagnosis and treatment items according to the user's personal physiological condition Personalized treatment avoids users' "excessive diagnosis and treatment", reduces the burden on doctors and patients, and avoids the waste of medical resources.

The invention belongs to medical instruments, and discloses a vaginal dilator with an optical fiber illumination device. An existing vaginal dilator has the defects that the existing vaginal dilator only has the vagina expanding function and does not have the illumination function, so that inspection is not complete, treatment is not complete or the treatment is excessive, and at the same time, labor and a specialized power source are wasted. The vaginal dilator with the optical fiber illumination device comprises an upper expanding sheet (1), a lower expanding sheet (4), a watching hole (2), a handle (6) and an adjusting bolt (5), wherein an optical fiber groove is formed in the handle (6), optical fibers (7) are arranged along the optical fiber groove to the tail end of the handle (6) and then connected with a coupler (9), the other ends of the optical fibers are provided with an optical fiber output end (3), and the optical fiber output end (3) is arranged inside the middle portion of the watching hole (2). The vaginal dilator with the optical fiber illumination device has the advantages of not only having the vagina expanding function, but also having the illumination function, being capable of illuminating tissue inside a vagina precisely, enabling a doctor to conduct operating conveniently, improving gynecologic examination precision and operation cure rate, lowering energy consumption of operating room illumination, and saving manpower.

The present invention provides methods to improve upon prostate cancer screening, thereby saving lives and reducing morbidities of unwarranted biopsies and over-treatment. The methods use a systematic analysis of the growth rate of PSA from cancer and PSA variation and the way in which they might be used to distinguish high-risk cancers from no cancer. Approaches include Dynamic-Differential Strategy, Dynamic-Differential Analysis, and Dynamic Analysis.

The invention relates to the technical field of medicine. At present, a USPIO (Ultra-small Super Paramagnetic Iron Oxide) preparation which has high in-vivo target tissue selectivity, high target tissue distribution concentration and high MR (Magnetic Resonance) imaging sensitivity is not reported. A stable and effective invisible nano-liposome preparation is prepared by taking an invisible nano-liposome as a vector, combining MR diagnosis with treatment and carrying USPIO and an anti-tumor medicament simultaneously. Due to the adoption of the invisible nano-liposome injection preparation serving as an MR contrast agent, the in-vivo tissue selectivity of the USPIO can be increased, the sensitivity is increased, and early diagnosis of diseases is facilitated; meanwhile, the invisible nano-liposome injection preparation is taken as a means for evaluating the curative effect of tumor therapy, so that the curative effect of tumor chemotherapy is monitored in real time, overtreatment of a patient is reduced, toxic and side effects are reduced, and the curative effect of tumor chemotherapy is improved.

The invention discloses an intelligent detection system for tracking and detecting prostate specific antigen (PSA) and a preparation method of its core module electrochemical sensor. The invention adopts electrospun nano-gold (platinum), magnetic nano-particles and other modified electrodes, and constructs an electrochemical sensor. The PSA intelligent detection system of the present invention tracks the PSA level of the screening object for a long time, and helps doctors to more accurately assess the risk of the screening object suffering from prostate cancer, so as to avoid false positive detection results and avoid over-treatment or even wrong treatment. The invention has the characteristics of sensitivity, specificity and high selectivity, and has important application prospects in the field of medical clinical diagnosis.
