On the morning of December 27, 2022, the Suzhou Institute of Biomedical Engineering Technology of the Chinese Academy of Sciences and ZD medical signed a strategic cooperation agreement in Hangzhou. The two parties will focus on the ophthalmic medical device industry and devote themselves to the innovation and breakthrough of new technologies in the field of ophthalmic clinical application to benefit the general public eye disease patients. For a long time, due to the highly subdivided and highly specialized ophthalmic diseases, people's awareness and attention to ophthalmic diseases is limited, resulting in a low level of ophthalmological diagnosis and treatment in my country, and the development of domestic ophthalmic drugs and devices is also slow At a very early stage, still import-dominated. The purpose of the two parties this time is to promote the innovation and breakthrough of new technologies of China's domestic high-end ophthalmic medical devices, and realize the provision of domestic excellent and high-quality ophthalmic medical devices and system solutions for eye disease diagnosis and treatment for the majority of eye patients. In the future, ZD medical will continue to increase investment in research and development, and through this cooperation, together with the strong scientific and technological research and development strength of Suzhou Institute of Medical Engineering, Chinese Academy of Sciences, will continue to develop and innovate, comprehensively promote, and improve new technologies in the fields of fundus, dry eye and optometry. Innovation and breakthroughs provide a more complete solution for the diagnosis and treatment of eye diseases for the majority of eye patients.

Ocular Coherence Tomography (OCT)  is an exciting new technique for examining the internal structures of the eye.  The most common present applications are looking in fine detail at the retina and optic nerve although anterior segment OCTs have also been developed to examine the cornea, iris and lens. OCT uses the principle of light interference to form a cross-sectional map of the retina or optic nerve.  A super-bright light source such as a special LED is used and a beam-splitter is used to form a reference and a scanning beam.  The reference beam is reflected by a reference mirror and is re-combined with the reflected scanning beam from the eye.  A computer analyses the interference patterns which result.  By varying the position of the reference mirror, different depths of the retina can be studied.  The scanning beam is traced across the retina by a computer controlled mirror which can move the point in a horizontal, vertical or any oblique direction.  The most common strategies used for looking at the retina with this type of OCT use a series of  intersecting scans in different meridians.  This is analogous to scanning from 12 O'clock to 6 O'clock and then from 1 to 7 and so on. Following the scan, a map is built up of the  area being scanned and presented in comparison to age-matched controls. The latest OCT scanners use a newer technique known as spectral domain OCT.  This is a technique where the individual freqencies of the light are used separately to build up an image without the need for scanning the spot on the retina.  This increases the speed, accuracy and reliability of the scan. As the OCT gives an accurate cross-section of the retina, it is very useful for the diagnosis of many diseases.  Such diseases include macular holes (a full thickness hole of the retina), central serous retinopathy (the accumulation of fluid beneath the retina) and macular edema from diabetes or retinal circulation problems. One of the most important new applications of the OCT is in the monitoring of the response of the retina to Lucentis.  Lucentis is an exciting new drug used in the treatment of wet age related macular degeneration (AMD).  Tiny quantities of the drug are injected into the eye to treat this devastating disease.  The OCT has been proven to be the best way of monitoring the response and determining the need for further injections. OCT testing is widely available, including at our clinic.

On the morning of June 14, 2022, the signing ceremony of the strategic cooperation between ZD Medical and Lumenis was held at the headquarters of ZD Medical. Mr. Zhai, Senior President of Lumenis Asia Pacific, said in his speech that he is full of expectations and confidence in this cooperation. China is a major global market for Lumenis, which attracts extra attention and is also an important strategic layout direction for Lumenis in the future. This cooperation is not only the first cooperation between Lumenis and ZD medical, but also the first cooperation between a global ophthalmic medical device company and a Chinese medical device company. ZD medical not only brings sufficient confidence to Lumenis in the new field of dry eye, but also plays a key role in research and development, academics, and even the future growth of both parties. Mr. Wang, chairman of ZD medical, said that dry eye is the most common and most neglected ophthalmic disease after myopia. It is also a kind of eye health problem that most needs to be paid attention to by the public. In our country, especially in the primary medical environment, the detection and treatment of dry eye syndrome is far from universal. Therefore, we hope that through this cooperation, we can build a complete dry eye solution platform together with Lumenis. At the same time, we also uphold an open and enterprising attitude and keep moving forward. Strive to build a national ophthalmic equipment brand that can represent Chinese technology. This cooperation is the first time that a Chinese local ophthalmic device brand has cooperated with a multinational ophthalmic device manufacturer, and it has opened up a precedent for domestic ophthalmic device brands to go international. It is believed that this cooperation will not only enhance the brand influence of both parties, but also lay a good foundation for the quality management and operation capabilities of Chinese high-tech ophthalmic equipment enterprises to reach the international level. Lumenis spans the world and penetrates into the Chinese market! ZD medical grew up in China, facing  embracing the world! Both ZD medical and Lumenis are willing to work together to fight for the eye health of the people in China and the world!

Diabetes mellitus is an increasing international health concern with no probability of termination.    The percentage of individuals with type 2 diabetes mellitus (T2DM) is 95% of those with diabetes mellitus in general .    The Middle East and North Africa have the second-highest rate of diabetes with 9.2%;    however, Iraq is one of the 21 countries in the region.    The number of deaths due to diabetes accounts for 10.7% of adult mortalities .    Individuals with T2DM constitute 8.5 - 13.9% of Iraqis .    A noticeable increase was recorded in the percentage of individuals with diabetes (35%) in 2011, compared to that of 2005 (11.9%), among Iranians within the age range of 25 - 70 years . Obesity or being overweight is the major modifiable risk factor for more than 90% of the patients with T2DM because it exacerbates insulin resistance .    Obese diabetic patients have more visits to hospitals and medical centers due to complications of obesity and diabetes, and the possibility of venipuncture to send laboratory samples or prescribe fluids and medications in this group of patients is high .    For nurses or even other healthcare providers, conducting laboratory diagnostic tests and procedures is considered a paramount portion of patient care that should be performed by following the highest quality of standard guidelines to avoid complications that might result from cannulation and inaccurate findings of laboratory tests . The literature confirmed that about 90% of patients in a hospital might need intravenous cannulation peripherally to administer medications or replace fluids.    In addition, the literature shows the maximum rate of mistakes in the clinical laboratory that involve sample collection by venipuncture, also known as phlebotomy .    The identification of the vein site is not simple.    Some elements affect the visibility of the patients’ vasculature, such as the difference in the skin character of young children (especially neonates), dehydration, and obesity (9). Due to high subcutaneous fat in obese patients, it is difficult to see veins and have access to blood vessels;    therefore, nurses face numerous problems in terms of time and technique when caring for these patients .    Furthermore, overweight and obesity exacerbate insulin resistance, which leads to the development of complications of diabetes linked to a poor vascular network . The use of certain devices or techniques, including tourniquet, local heat , ultrasound , and transilluminating devices , will help have better access to the veins of the limbs.    A transilluminating device is one of the technical evolutions which employs near-infrared light-emitting diodes (NIR-LEDs) to show superficial veins with hemoglobin absorbing the light generated and producing a view on the surface of the skin, which has lately been advanced .&nb...

In 2017, the government had decided to name August 19th as the Medical Workers' Day, in the purpose of showing respect of the work of the doctors.Today is the sixth Chinese Medical Workers' Day. Noting that medical workers are a vital force in advancing the cause of healthcare, Xi said since the COVID-19 outbreak, a great number of medical workers have raced against time and fought tenaciously against the virus at the frontlines. They have made significant contributions in fighting the epidemic, and demonstrated the noble spirit of giving priority to saving lives with total devotion and ultimate love. As they wear protective suits and masks most of the time, I can't see their face. But in my heart, they are the loveliest people.

ZD medical invited Professor Shi to participate in the online teaching activities On the evening of August 9.During this period, the number of participants reached 2600, and the number of likes exceeded 36000. The teacher answered questions patiently, and the on-site learning atmosphere was strong. Professor Shi Dong is a senior chief physician of the Fourth Affiliated Hospital of China Medical University and a master's supervisor. Doctor of Ophthalmology, Tohoku University, Japan. He is good at the diagnosis and surgical treatment of common eye diseases such as fundus disease, cataract and glaucoma. The course contents range from "Fundamentals of Ophthalmology" to "OCT clinical skills and precautions" and then to "interpretation of abnormal OCT images". Professor Shi's sharing is detailed and thought-provoking. We asked Professor Shi to answer three questions on the spot: Q&A: 01. Q:Can OCT replace or partially replace fundus examination? A:OCT and fundus examination are complementary, The combination of the two examination can help clinicians diagnose the disease more effectively. 02. Q:How to judge whether it is bleeding or exudation on OCT? A:When OCT passes through the fundus line, the yellow color is likely to exude, and the red color is bleeding. 03. Q:How to better master the operation of OCT? A:① Understand the patient's condition, main complaint, medical history and general condition before reading the film, and have a general diagnosis and treatment direction for the patient; ② Be familiar with the principle of OCT imaging and the meaning of representatives at all levels; ③ Combining the pathological characteristics and pathogenesis of various diseases can better help us to interpret OCT imaging. After the event, Professor Shi sent sincere wishes and best wishes to ZD medical and all domestic technology manufacturers. ZD medical also presents its corporate vision here: to become the leader of domestic ophthalmic devices and strive for the cause of human eye health.

At the beginning of the new year when China and Beijing were hidden in winter, the second ophthalmic equipment clinical application study class held by the Department of Ophthalmology of the First Medical Center was started On January 4th. In his opening remarks, Prof. Li Zhaohui, chairman of the conference and director of the Department of Ophthalmology of the First Medical Center, said that this conference is a rare academic one dedicated to ophthalmic equipment in the country so far. There are many kinds of ophthalmic equipment. How to use it well and correctly analyze the inspection results, so as to better improve the clinical diagnosis and treatment ability of ophthalmology, is a real problem currently faced. The conference is divided into four periods according to the characteristics of ophthalmic equipment: ocular surface cornea period, refractive cataract period, fundus disease period and equipment practical skills period. The lecturers included not only domestic clinical celebrities, academic elites, but also engineers from manufacturers. Everyone conducted a comprehensive interpretation and in-depth discussion around the basic application and latest progress of ophthalmic examination equipment. In the Wetlab area, unlimited pig eye operation and experience use of phacoemulsification machine enable students to combine knowledge with practical operation, which benefits everyone a lot. Confocal microscopy uses laser light source-assisted tomographic scanning technology to provide great help for the diagnosis of difficult corneal endothelial lesions. Professor Hong Jing from Peking University Third Hospital described the differentiation about the cellular morphology of endothelial lesions (eagle eye cells, Descemet's warts, etc.) under confocal microscope by showing confocal pictures of typical cases such as FUCHS corneal endothelial dystrophy, posterior pleomorphic corneal endothelial dystrophy and corneal endotheliitis. She also discovered cell size and cell count methods and diagnosis and treatment ideas, and put forward a new strategy for the diagnosis of corneal endothelial decompensation by combining aqueous humor virus detection and confocal microscopy, which provides a new idea for the analysis of the causes of corneal edema after cataract surgery. With the popularity of electronic products and the stressful daily work, dry eye brings great trouble to many people. Professor Wang Liqiang from the First Medical Center systematically expounded dry eye from the epidemiology, definition, pathogenic factors and traditional inspection methods, and described the diagnosis process of dry eye in detail combined with the DEWS II dry eye classification. Subsequently, the advantages of the ocular surface comprehensive analyzer were explained through specific examples, including objective recording of tear film break-up time, quantitative determination of tear river height, a comprehensive meibomian gland analysis system, and objective analysis ...
