A homogeneously illuminating ophthalmic instrument includes an illumination device having a source of illumination, a homogenizing unit and a projection device, at least one organic or inorganic source of radiation with spectrally selective emission being used as a source of illumination. The illumination generated in this way enables correspondingly adapted visual and/or digital observation, recording or display of the examined regions of the eye by a visualizing unit.

The invention discloses application of MYOZ1 in diagnosing and treating parkinsonism, belonging to the technical field of new application of genes. The experiment proves that the MYOZ1 gene expression in the blood of a parkinsonism patient is enhanced as compared with a normal person, which indicates that the MYOZ1 expression level in the blood can be detected to diagnose whether a subject suffers from parkinsonism. The in-vitro MTT experiment detect that the MYOZ1 gene expression is not beneficial to growth of human neuroblastoma cells. Therefore, the MYOZ1 has favorable development and application prospects in preparing products for diagnosing and treating parkinsonism.

The invention discloses a targeted polypeptide for vitro and vivo early diagnosis or treatment of lung cancer, belonging to the medicine technical field. The polypeptide is dodecapeptide. The invention also discloses the application of the targeted polypeptide. The targeted polypeptide is applied to a carrier of the targeted therapy of the lung cancer or the preparation of anti-cancer drugs, or used as the medicine of early period and the middle period diagnosis of the lung cancer. The polypeptide provided by the invention is small micro molecule antibody and has smaller antibody molecular weight and strong penetrating power, is easy to reach tumor tissues and can be more sensitive to diagnose the tumor apart from having the advantages of the traditional antibody medicine, thus being in favor of the early diagnosis of the tumor. The polypeptide has good targeted function of the tumor, is suitable for the targeted treatment or the carrier of the targeted treatment and has wide application prospect.

The invention relates to a swine flu virus real-time fluorescent RT-PCR isotyping kit, in particular to a kit for performing isotyping of swine flu viruses by using a one-step method real-time reverse transcription-polymerase chain reaction (RT-PCR) technique. The kit has high sensitivity and specificity. Through the isotyping of the swine flu viruses in respiratory tract specimens and serum and lung tissue samples and other samples by using the kit of the invention, the early-period quick diagnosis of the swine flu viruses is realized, and the trend of the swine flu viruses can be monitored.

The invention belongs to the field of animal disease diagnosis, and particularly relates to a marker GP50 for coenuriasis, as well as a coenuriasis diagnosing kit for diagnosing coenuriasis. According to a coenuriasis indirect ELISA diagnosing method, the sensibility reaches 95%, and the specificity reaches 92.6%. Monitoring of a serum antibody of a goat artificially infected with taenia multiceps discovers that the GP50 antibody values in the whole detection period after infection are all positive. Therefore, the GP50 recombinant protein can be used as the coenuriasis marker, and is used for diagnosing coenuriasis. According to the coenuriasis indirect ELISA diagnosing kit, the coenuriasis can be quickly, sensitively and specifically used for diagnosing coenuriasis, and a foundation is laid for early diagnosis and the treatment effect evaluation of coenuriasis infection.

The invention discloses a molecular marker-EAPP gene for early diagnosis of the Alzheimer disease. An experimental result shows that the mRNA level of the EAPP gene in blood of the patient suffering from the Alzheimer disease is remarkably lower than that of normal people, so that whether a tested person has the risk of the Alzheimer disease or not or whether the tested person has suffered from the Alzheimer disease or not is judged by determining the expression level of the EAPP gene in the blood of the tested person. The EAPP gene can be used for preparation and application for the patient suffering from the Alzheimer disease or the crowd with the high Alzheimer disease risk so as to be used for treating the Alzheimer disease or preventing the Alzheimer disease. The new diagnosis method is provided for diagnosing the Alzheimer disease clinically and the new candidate medicine is provided for treating the Alzheimer disease.

This invention relates to the detection and diagnosis of tuberculosis. More specifically, the invention relates to new biomarkers and combinations thereof that enable the accurate detection and diagnosis of tuberculosis.

The invention discloses application of a THBD gene in Parkinsonism diagnosis. The content of the THBD gene in blood of a Parkinsonism patient is remarkably different from that of a normal person, andthe Parkinsonism patient can be distinguished from a non-Parkinsonism patient according to the difference. The invention further discloses a diagnosis product of Parkinsonism. By means of the diagnosis product, the aim of realizing Parkinsonism diagnosis by detecting the THBD gene in blood can be achieved.

The invention discloses a molecular marker in blood serving as a diagnosis index of respiratory syncytial virus infection. The molecular marker in blood is TYMS. Experiments prove that the content ofTYMS gene and TYMS protein in the blood of people infected with respiratory syncytial virus obviously increases compared with that of normal people. Due to the expression difference between TYMS geneand TYMS protein, the content increase can serve as an index for distinguishing the people infected with respiratory syncytial virus from the non-infected people. Compared with traditional virus antibody detection method and virus antigen detection method, the non-virus index in the blood is adopted for virus detection by the invention, and high-sensitivity detection can be realized.

The invention belongs to the field of medical instruments and particularly relates to a glioma diagnosis and treatment device which comprises a photodynamic irradiation catheter and an implantation catheter mutually matched in use. The photodynamic irradiation catheter comprises an irradiation catheter body, and a photodynamic irradiation optical fiber is arranged in the irradiation catheter body;one end of the photodynamic irradiation optical fiber is positioned on the lower end face of the irradiation catheter body, and the other end of the photodynamic irradiation optical fiber is connected with a photodynamic interface; the irradiation end of the irradiation catheter body is also provided with an imaging component; an illuminating light source is further arranged at the illuminating end of the illuminating catheter body. According to the invention, the split type photodynamic irradiation catheter and the implantation catheter are adopted, the photodynamic irradiation catheter andthe implantation catheter are simple in structure, the device is a microtrauma diagnosis and treatment instrument aiming at tumor recurrence, which can be applied to the head of a patient after gliomaremoval operation for a long time, can be applied repeatedly and minimally invasive, is sensitive, fast and accurate in diagnosis and treatment. The human body implantation part is simple in structure and small in size, can be implanted for a long time, and does not influence the appearance and daily life of the patient.
